DYNAMIC RADIO-SIGNAL MEMORY DEVICE Russian patent published in 2003 - IPC

FIELD: radio signal generation and processing. SUBSTANCE: dynamic memory device has transmitting optical module 3, N fiber-optic delay lines 9, control unit 5, and photodetector 6 whose output functions as device output; novelty is introduction of broadband amplifier 1, power splitter 2, fiber- optic amplifier 4, Y-type isolating fiber-optic directional coupler 7, 2N fiber-optic switches 8, N 1 X- type fiber-optic directional couplers 10, and Y-type fiber-optic adding directional coupler 11, input being input of broadband amplifier 1 whose output is connected to input of power splitter 2; first output of the latter is connected to power input of transmitting optical module 3 whose optical output is connected through fiberoptic amplifier 4 to input of Y-type isolating fiber-optic directional coupler 7. EFFECT: enlarged capabilities of controlling copy sequence shaping process at high identity of copies and low optical fiber consumption. 1 cl, 33 dwg
